If you follow Busy Philipps on Instagram, you know she posts a lot of workout selfies. And it turns out, she actually has a great reason for doing so. The actress recently took to social media to talk about her fitness posts—and why they mean so much to her.

"Someone asked me if people like my sweaty Instagram stories," Philipps wrote in the caption. "My feeling is that, honestly, I don't really care all that much. I post those for myself—as a 'f*ck yes!' for showing up." She explained that she has anxiety and a "tendency toward depression," but fitness helps her keep going.

"I have found if I sweat like this EVERY SINGLE DAY, I feel better, I'm calmer, I'm a better mom, and those fogs of anxiety or sadness seem a little lighter," Philipps said, explaining that when she works out regularly, she's less likely to pick her skin or engage in binge eating. She also just feels better in general. "My goal is to feel the best I can in my body and my brain for the rest of my life."

Anxiety is the most common mental health condition in the United States, and it currently affects 40 million American adults, according to the Anxiety and Depression Association of America (ADAA). There are many different kinds of anxiety, but most are characterized by prolonged feelings of fear, nervousness, or concern. Depression is also quite common, affecting 15 million Americans adults, according to the ADAA. Depression involves symptoms like sadness or hopelessness, changes in appetite, and difficulty sleeping. While it's normal to experience these sometimes, if these symptoms last longer than two weeks, they could be a sign of depression.

Worth noting: Exercise has been linked to mental health benefits, like improved mood and stress relief. And many mental health experts actually recommend that patients exercise (in addition to taking medication and/or going to therapy) to treat depression. Still, it's important to remember that what works for someone with anxiety and depression won't necessarily work for everyone. While Philipps finds fitness to be therapeutic, someone else might find that same respite in watching HGTV or reading books.

There's no one-size-fits-all solution, and it's awesome that Philipps has found this outlet.
